i TO ALL WHOM II MAY CONCERN: i

Be it known that I, JOHN HENRY SMITH, of the city and county oi' Allegheny, and Stato of Pennsylvania,

have invented a new and useful Improvementjn Vessels for Transporting Oilsand Burning-Fluids; and I do hereby declarethat the following is a full and exact description thereof, reference being had to the accompanying drawings, and to the letters and iigurcs of reference marked thereon. i y l The nature of my invention consists in providing the hulls of ships and other vessels with acompartment for oils and burning-fluids, said compartments being furnished with supply and discharge-pipes, and protected with water, in the manner hereinafter described. A Y

To enable others skilled in the art to make and use my invention, I will proceed to describe-its construction and operation. In the accompanying drawings, which form part of my specification- Figurel is a'longitudinal section of a ship provided with my improvements.

Figure 2 is a transverse secti'oniof the same. i A

Figure 3 is an 'end view ot' a furnace, which may be used for burning oil, or other inilammahle matter, in the boiler-furnaee of the ship or other vessel.

I provide the hull of the ship with a compartment` for the oil, and cover it with n. water-chamber. D repre; sents the oil-compartment, and h represents the water-chamber, which is provided withy small ports, marked 5, for keeping the water fresh. On the deck or covering of the water-chamber h is the boiler-furnace, marked 3. The boiler-furnace consists of a shallow iron vessel, made in-the forni represented'in the drawings, which willV readily be understood by the skillful mechanic.A This vessel should be'so constructed that it will resist the action Vof' the fire. This may he done -by thense'o tire-brick, or the-application of-lwater-lining. In one endof this boiler-furnace I make a number of ilanged openings, marked 2, into which enter small pipes, marked x, which are connected to a T-shaped pipe, I3, which passes through the water-chamber-to the oil-compartment D, entering the oil-compartment in the converted' part of the bottom of the water-chamber h.'y On the `upper deck of the ship are ,placed an oil-reservoir, e, and water-rescrvoirsf and g, to which are attached pipes A, C, and C', which lead down into the oil-compartment D. All the. pipes leading to `the oil-compartment are provided with valves, marked 1; the steam-boiler is marked 4. i

As the construction and arrangement o'f the several parts of my invention will readily hel seen and understood by the skillful mechanic, by reference to the accompanying drawingaI will therefore proceed to describe the operation 'of my improvement, whicli is as follows: :The oil or burning-fluid` is put inthe rescrvoii.e,.and

, passes down thc pipe A, and, when the compartment D is filled, the valvefl of the pipe A is closed. I then {ill thc'reservoirsf and g with water, and open the valves of the pipes C and C', which will bring a pressure to bear on the oil which will be in proportion to the height of the reservoirs from the oil-compartment. 4 When I desire to raise steam, by the use oft he oil orbnIfnin'g-iluid Vthat is in thecompartment D, I openthe valve 1 of tho pipe B, and the oil or other inflammable matter will iiow upwards through the pipe B, and through its branches rv. I then ignite the oil by any of the known means; 'lhc flanged openings 2 will direct the air-'to -the desired points, around the branches a: of the pipe B, and the low of the oil to the furnace and fire can bc regulated and controlled by the valve 1, in pipe B. The supply of water to the rcservoirsf andy will depend on the consumption of the oilfrom the department D. When the oil is all consumed, or 'otherwise withdrawn from the' compartment D, the watcrwliich has taken its place can be pumped out :It will.

f 5 From the above4 descriptiom'and by reference to the accompanyingdrawings, the mechanic-will scc at a glance that iniiammable oils and fluids can be carried on -ships and other vessels with safety to all ou board of such ships and vessels, and also that inflammable liquid matter of les's gravity than water can be used as fuel for any heating purpose, with ease and perfect safety to the ship and vessel, and all 'on board the ship or vessel.

The-size, form, and the arrangement of the several parts of my invention, I leave to the taste, judgment, and skill of the mechanic', and those who muy use it' for the purpose sctffortli and described;l y Having'thus described the nature, construction, and operation of my improvement, whatl claim as of my Invention is- Providing the hulls ot'- ships and other-,vessels with a compartment forioilshand burning-fluids, said com- Parimenti being protected with4 water, and furnished with-supply and discharge-pipes, suhstantiallyas herein described and for the purpose set forth.
